closes #363
Summary
Adds a backend contract execution sandbox service for Soroban WASM execution.
Introduces POST /api/v1/sandbox/execute.
Adds bounded execution controls for WASM size, argument count, argument size, CPU, memory, and timeout.
Returns structured execution results including status, diagnostics, resource usage, result XDR, and WASM SHA-256.
Adds unit and integration-style tests for sandbox behavior and API routing.
Reason
This implements the MVP-critical backend sandbox capability required for safely executing contract WASM in a controlled environment while preserving architectural boundaries and API consistency.
